ftb8000b系列儀表使用的多射流原理，已成為*的標準很多年了。這種儀表稱為其廣泛，簡單，精度和低質(zhì)量的水。葉輪的中心是一個環(huán)形射流，在另一層面和出口射流進氣喉。一個齒輪驅(qū)動寄存器積算儀表盤。脈沖輸出，一個圓盤的齒輪代替，使磁鐵是由封裝的傳感器檢測到的透鏡的外螺紋。脈沖頻率由齒輪確定，撥號齒輪上放置。改變脈沖的速率不需要工具，可在現(xiàn)場完成的。
機械，所有ftb8000b米是一樣的。之間的差異- PR，PT，和標準模型中的傳感器。PR模型米使用固態(tài)，持久的霍爾效應傳感器，這需要功率。PT模型米用2線簧片開關。他們提供干接點閉合，不需要電源。ftb8000b米總計只有基本沒有輸出。沒有安裝水表的上方或在地方的泄漏會造成損傷。
